Do an internet reinstall. Restart the computer, hold down the Command (⌘) – Option (⌥) – R combination immediately upon hearing the startup chime. Hold the keys until the animated globe appears on the screen. It will say “Starting Internet Recovery,” follow directions. This will take some time to do so don’t be in a hurry.
